The Eclipse concentrator fits neatly into the main compartment and is secured with compression straps and a top flap that clips shut. A clear plastic window on the top flap allows for an unobstructed view of the Eclipse's control panel; and a Velcro flap provides easy access to the Eclipse Power Cartridge.

Went to Wales for World Cup - The pack was a winner!!!Written By: Momster, Jolly ol 10/9/2015
This pack took the Eclipse concentrator and 4 extra batteries to Millennium Stadium. Wouldn't have been able to do without it! Checked out many backpacks and other solutions, but always came back to this pack. Like anything "medical", the price is honestly too high for what it is, but as long as it holds up, we'll consider it worth it.
For long-hauls or for trips where you need to pack extra batteries and other necessities - this pack is what you need.
